Dermatologists recommend that everyone protect themselves from the sun by using sunscreen, wearing closely woven sun protective clothing, sunglasses with a UV filter and, of course, a broad-brimmed sun hat. Tilley brimmed hat fabrics have been tested and certified to provide a UPF of 50+, the maximum rating given.
What is UPF? Is it similar to SPF? UPF stands for Ultraviolet Protection Factor. A UPF rating is granted to apparel that has been tested and proven to block a certain amount of ultraviolet radiation. UPF is like SPF, except that UPF means the UV testing was conducted on fabric rather than peoples skin. An SPF rating only applies to
lotions applied directly to skin, not fabrics. The fabric of Tilley brimmed hats are tested and certified to provide a UPF of 50+, the maximum rating given. Tilley clothing fabric is rated for UPF protection between 15 & 50+. Check product details for specific ratings.
